Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1, 2, 3, the utility model discloses a multi-functional intelligent regulation controller, keep apart module 6, signal display part 2, signal locking module 3, communication port 4 and ARM treater 5 including controller input/output part 1, input/output, ARM treater 5 keeps apart module 6 and controller input/output part 1 electricity through input/output and is connected, and ARM treater 5 is supplied power by signal locking module 3.

The input and output part 1 of the controller comprises a 4-20ma input and a 0-10V input, and the output part comprises a 4-20ma output and a 0-10V output; the device can be compatible with a conventional input and output form, and the universality of the controller is ensured.

The signal display part 2 comprises a nixie tube display screen 21 and a data source switching button 22, wherein the nixie tube display screen 21 is used for displaying signal percentage, and different input and output signal sources can be browsed through the data source switching button 22.

As shown in fig. 3, the signal locking module 3 is a key part of the controller, and the module includes a power switching part and a storage power supply, when the module loses power, the power switching part is automatically switched to the storage power supply, so as to keep the normal output of signals of the output part of the controller, ensure that the equipment can keep the existing state unchanged, and inform the customer of maintenance in an audible and visual alarm manner.

The power supply switching part is characterized in that a mains supply is switched to a storage power supply through a switch and a coil, the mains supply is normally used, and the storage power supply is used after power failure.

The communication port 4 is an RS485 interface module and is used for transmitting signals and receiving computer signals.
